I still firmly believe that it would be way more efficient to fetch all those branches into _one_ proxy repository. Especially since you can reuse the objects with an alternate, which has an additional benefit over your approach.

And _then_, you can make a wrapper script, which guarantees that the alternate is set, and that the ref is actually fetched from the proxy.
